The Differences between fusion and fission is given here. Fusion and fission are two different physical and nuclear processes.

Fusion
In nuclear physics, it is the process by which several atomic nuclei of similar charge and form a heavier nucleus. During this process, a large amount of energy is released or absorbed. This allows matter to enter a plasma state.
The fusion of nuclei with a mass less than that of iron releases energy. If the fusion occurs in a core heavier than that of iron, the fusion will absorb energy. In nature, nuclear fusion occurs in the stars inside, at temperatures close to 15 million degrees Celsius. Fusion reactions are called thermonuclear. In controlled environments, fusion has been achieved. The three advantages of this process are:
- It does not produce hazardous waste.
- In abundant.
- Nuclear fusion facilities can be shut down without risk.
Fission
Fission is a nuclear reaction. This means that fission takes place in atomic nuclei. It occurs when a heavy nucleus splits into smaller nuclei. It produces by-products such as free neutrons, photons, or gamma rays and nuclei fragments such as alpha and beta particles. Heavy nuclei generate an exothermic process that releases amounts of energy. The process generates much more energy than common chemical reactions. This reaction heats up space where fission occurs. It can be produced by various methods such as bombarding the nucleus of a fissile atom with energy particles such as free neutrons.
Differences between fusion and fission
- Infusion, nuclei with less weight than iron release energy, and those with greater weight absorb energy.
- In fission, nuclei with less weight than iron absorb energy and those with greater weight release energy.
- Fusion forms heavier nuclei.
